Up for sale is a rare vintage Casio A280 Calendar Memo men’s digital watch, powered by Module 551 and made in Japan. Produced in the early 1980s, this Japan Domestic Market (JDM) model is known for its distinctive scrolling monthly calendar display along the bottom of the LCD — a clever and innovative feature from Casio’s early digital era.

The watch is in full working condition. All functions — including timekeeping, alarm, stopwatch, and the signature calendar memo — operate exactly as they should.

All parts of the watch are original, including the stainless steel bracelet and CASIO-signed clasp — a detail that is increasingly hard to find intact on examples of this age.

The watch is in good physical condition but does show signs of use consistent with its vintage nature. The photos best describe its overall appearance.
